The scenario
User needs a reliable DC schematic to wire four 12V batteries into a series-parallel bank for a 24V off-grid system, such as an RV or solar backup.
What is in this drawing
Read the decisions behind it.
01
Configured as 2S2P to deliver 24V while doubling the amp-hour capacity.
02
Each series string connects to shared VOUT and ground rails to ensure balanced charging and discharging.
03
All negative terminals are tied to a common ground reference (net '0') for safety and consistency.
Off-grid solar installations, marine battery banks, RV house banks, or any 24V DC supply built from 12V deep-cycle lead-acid batteries.
